TECHNICAL FIELD Description of Related Application

This application claims the benefit of Japanese Patent Application No. 2015-056370, filed Mar. 19, 2015, which is hereby incorporated by reference herein in its entirety.

The present invention relates to a charging apparatus, a method, a system, and a non-transitory medium.

Background

First, an Evolved Packet Core (EPC) network accommodating an LTE (Long Term Evolution) radio access network will be described. FIG. 1 schematically illustrates how terminals 1A and 1B contracting with telecommunications carriers A and B respectively connect to the Internet, respectively. A communication operator that possesses a communication infrastructure such as a base station, a core network, or the like, is called a carrier or MNO (Mobile Network Operator) carrier. Meanwhile, a communication operator that borrows a necessary communication facility(s) such as a wireless infrastructure including a base station or the like from a MNO carrier, for example, and provides a mobile communication service under its own brand is called a MVNO (Mobile Virtual Network Operator) carrier (virtual communication operator).

EPC 20A, which is a core network of a carrier A, includes, for example, SGW (Serving Gateway) 21A, PGW (Packet Data Network) Gateway 22A, MME (Mobility Management Entity) 23A, HSS (Home Subscriber Server) 25A, PCRF (Policy Charging Rules Function) 24A, PCEF (Policy and Charging Enforcement Function) 26A, and the like. Representative elements of the EPC will be briefly described here (for details, reference will be made to the 3GPP (3rd Generation Partnership Project) specification (3GPP TS 23.401 V9.5.0 (2010-June)), etc., for example). MME 23A performs various processes such as mobility management and authentication of a user equipment (UE) 1A, setting of a user data transfer path, and the like. MME 23A cooperates with HSS 25A to perform user mobility management, authentication, and the like. HSS 25A holds user profile information (including contract information, authentication information, etc.). SGW 21A performs transmission and reception of user data to and from a base station (evolved NodeB: eNB) 10A and performs setting and release of a communication path between SGW 21A and PGW 22A. PGW 22A connects to a packet data network (PDN) such as IMS (IP Multimedia Subsystem) and the Internet 30, and performs allocation of an IP (Internet Protocol) address (private IP address) to the terminal 1A. PCRF 24A is a policy control apparatus that determines policy control such as QoS (Quality of Service) and a charging control rule. PGW 22A and SGW 21A perform policy control on a per packet basis, for example, based on notification information (policy) from PCRF 24A. PCRF 24A determines a policy regarding access control of a user IP flow and QoS parameter value, and PCEF (Policy and Charging Enforcement Function) 26A performs according to the policy, the access control for a user IP flow and the corresponding QoS control. In FIG. 1, the alphanumeric characters S1, S5, S8, SGi, etc., attached to signal lines represent interfaces. “U” of S1-U represents a user plane (User Plane). S1-U represents a S1 user plane interface (where a user IP packet is transferred) between a base station (eNB) and an SGW.

Regarding charging, there are provided an online charging system (Online Charging System: OCS) that captures a communication amount of a terminal in real time to compare the amount with a prepaid fee, and an offline charging system (Offline Charging System: OFCS) that accumulates a communication amount, on a monthly basis, or the like, after a subscriber uses the network resources. An online charging system (OCS) (not illustrated) manages a communication amount to carry out conversion of the communication amount with a prepaid balance. PCRF 24A cooperates with OCS (not illustrated) to manage a communication policy. PCEF 26A applies the communication policy to a packet transfer in PGW 22A.

It is noted that PCEF 26A may be implemented in PGW 22A. For example, a high-speed communication policy is applied to a terminal 1A with a prepaid type charging contract, OCS instructs application of a quota of 1 GB (Giga Bytes), for example, to PCEF 26A, which applies a high-speed communication. If there is a prepaid balance (corresponding communication amount), high-speed communication is allowed, and when the prepaid balance is 0, that is, when 1 GB is used up, PCRF 24A switches to a low-speed communication policy and applies low-speed communication. It is noted that the quota may be a calling time or the like.

PCRF 24A includes PCRF database 24A-1 including a statistical information table 24A-2 for holding statistical information such as packet count, packet fee, call time, call charge, etc., and contract information such as packet plan. and a contract information table 24A-3 for holding contract information such as a packet plan and a call plan. EPC 20B, which is the core network of the carrier B, has the same configuration as that of EPC 20A, which is the core network of the carrier A, described above, so the description of EPC 20B will be omitted.

The terminal 1A contracting with the carrier A and the terminal 1B contracting with the carrier B are individually charged from the carrier A and the carrier B, respectively.

For details of OCS, reference may be made to 3GPP Specification (3GPP TS 32.296 V12.3.0 (2014-December)) and the like. For details of PCRF, PCEF, etc., reference may be made to the specifications of 3GPP (3GPP TS 23.203 V13.2.0 (2014-December)) and the like.

DETAILED DESCRIPTION

In the following, a related invention as a premise of the invention will be described, and then embodiments of the present invention will be described.

In SDN (Software Denned Network)/NFV (Network Function Virtualization), a plurality of network appliances that individually require a casing are integrated on a server using a virtualization technology. For example, virtualization of EPC (Evolved Packet Core) or the like, which is a core network of a communication operator, is in progress. In a virtualized EPC (Virtualized EPC: vEPC), for example, at least one or all of the functions of nodes such as SGW, PGW, MME, HSS, PCRF and the like, are implemented in a software-based manner by an application running on a virtual machine (VM). A software that implements a virtualized network function is called VNF (Virtual Network Function) (one VNF is realized using one or more VMs). An execution infrastructure of a VNF, such as a hypervisor, which is a virtualization mechanism for virtualizing hardware resources (computing, storage, network interface controller (NIC), etc.), and hardware resources to be virtualized, is called a NFVI (Network Function Virtualization Infrastructure) (reference may be made to Non-Patent Document 1 for details).

FIG. 2 is a diagram illustrating the related invention as a premise of the present invention. In the following, it is assumed that a data center operator having a data center (DC) within a business establishment is a cloud operator that provides various services (for example, cloud services such as file storage, data sharing, electronic-mail, use of a server, etc.) to clients. A virtual EPC network (vEPC) 40 is constructed on a server (not illustrated) in the data center (DC) 50, whereby, as an MVNO (Mobile Virtual Network Operator) carrier C, a communication service is provided to a client (contracting with the MVNO carrier C).

In FIG. 2, a communication facility such as a base station 10A, EPC (A) 20A, or the like is a facility owned by an MNO carrier A, and a communication facility such as a base station 10B, EPC (B) 20B, or the like is a facility owned by an MNO carrier B. In FIG. 2, EPC (A) 20A and EPC (B) 20B are the same as EPC (A) 20A and EPC (B) 20B in FIG. 1 and the description thereof will be omitted. A cloud operator (MVNO carrier C in this example) borrows the base station 10A and the base station 10B, etc., lent from the MNO carrier A, and MNO carrier B, respectively. Here, terminals 1A and 1B of a user contracting with the MVNO carrier C are assumed to be SIM (Subscriber Identity Module)-free terminals, on each of which a SIM card (Subscriber Identity Module card) of the MNO carrier A or B versions is inserted. In this case, the terminals 1A and 1B respectively establish radio links (RRC (Radio Resource Control) Connected state) with the base stations 10A and 10B owned by the carriers A and B, respectively, and connect through the EPC networks 20A and 20B and via the Internet 30 to the virtual EPC 40 on a server (not shown) installed in the data center 50 of the cloud operator. The terminals 1A and 1B receive connection service via the virtual EPC 40 to the Internet 31, a cloud type content cache service, etc., provided by the cloud operator.

Here, let the MVNO carrier C, be such a carrier, though not particularly limited thereto, that integrates various services, for example,

-   -   Application store (purchasing and downloading of Application);     -   Electronic-book store;     -   Delivery services of movies, television, music, etc.;     -   Purchasing of terminals (smart phone, tablet, PC (Personal         Computer), etc) (services including electronic payment and         electronic commerce), and establishes an integrated service         providing site for providing the service to the terminals 1A and         1B via a gateway 41.

The MVNO carrier C, which is an owner of the data center 50, provides various cloud services. Therefore, contents or the like that the user has purchased using the terminals 1A and 1B are stored and managed on the cloud (data center 50), and using the same user account, are shared by a plurality of terminals (for example, smart devices, a tablet, or a PC (Personal Computer), or the like that the user owns).

In the related invention of FIG. 2, when the same user possesses the terminals 1A and 1B, usage details such as monthly (billing statement) are separately sent from the MNVO carrier C to the user, for each of the terminals 1A and 1B, respectively. Alternatively, a current usage status (communication amount, communication charge, etc.) of each of the terminals 1A and 1B may be sent online. It is noted that In FIG. 2, in the EPC networks 20A and 20B of the MNO carriers A and B, internal nodes are omitted and a PCRF database 24A-1 of the EPC network 20A of the carrier A and a PCRF database 24B-1 of the EPC network 20B of the carrier B are illustrated. In FIG. 2, the number of MNO carriers is not limited to two, but it may, as a matter of course, be three or more.

In some cases, the MVNO carrier C sells a SIM card for passing through the communication network of the MNO carrier A (base station 10A and EPC 20A in FIG. 2) and the communication network of the MNO carrier B (base station 10B and EPC 20B in FIG. 2). As a charging system, there may be a monthly payment system, such as 6000 yen per month, an upper limit of a communication amount being 7 GB/month, and no speed limit up to the upper limit, wherein when the communication amount exceeds the upper limit, the communication speed is set to low speed (128 bps (bit per second)). Alternatively, in a prepaid system, for example, a disposable SIM card (for example, 2000 yen) is used, and the communication capacity is, for example, 1 GB.

It is noted that in FIG. 2, the EPC network in the data center 50 is composed of a virtual EPC, but it need not be a virtual EPC. Further, in the data center 50, the functions of the gateway 41, routers and various other servers may be virtualized on one or more server apparatuses.

<Basic Mode>

FIG. 3 is a diagram illustrating an example of a basic mode (concept) of the present invention. The basic mode of the present invention may be implemented in the system of FIG. 2, for example. Referring to FIG. 3, the MVNO carrier C borrows communication facilities from the MNO carrier A and the MNO carrier B, respectively. In the example shown in FIG. 3, for example, the MVNO carrier C borrows X million lines lent from the MNO carrier A and Y million lines lent from the MNO carrier B. MVNO carrier C can provide (X+Y) million lines. The MVNO carrier C performs charging management of a terminal into which a SIM card provided by the MVNO carrier C is inserted, in a unified manner (centralized manner), irrespective of whether the SIM card is a carrier A version or a carrier B version. At that time, for example, basic charge, call charge, communication charge, etc. can be collectively charged based on a user account registered at an integrated service providing site provided by the data center 50 (FIG. 2) owned by the MVNO carrier C. A user account established at the integrated service providing site may be a mail address of a free e-mail such as Web mail, for example. In this case, notification of usage details, etc. to the user may be made by free e-mail using this user account. Further, the user account may be an arbitrary ID (user ID or the like) associated with a mail address as described above.

A user using the integrated service providing site of the MVNO carrier C (cloud operator) can prepay for various services provided by the integrated service providing site (prepaid system). In this case, a charge for a SIM card provided by the MVNO carrier C contracted by the user may be automatically withdrawn from the prepaid balance. In this case, a withdrawal may be made based on a measured rate system, such as 1000 yen for communication amount: up to 1 GB, 3000 yen for communication amount: up to 4 GB, etc., or a flat rate system such as 2,500 yen per month. As a special option for a user of a SIM card(s), such a license for using Wi-Fi (Wireless Fidelity: Wi-Fi is a registered trademark of Wi-Fi Alliance)-calling (Wi-Fi is used to make calls and SMS (short message service) A function to transmit and receive data) may be provided free or charged (fixed rate or measured rate) to the user, and if the license is charged, it may be added to the charge.

According to the basic mode of FIG. 3, in order to charge based on a user account, in a case where the user owns a plurality of terminals and uses one ID (common user account), charging for the plurality of terminals can be unified (consolidated) as charging for the common user account. For example, assuming that a user makes a contract with a MVNO carrier C (cloud operator) with a plan of 1,000 yen for communication amount up to 1 GB, and that the user has a smart phone and a tablet, the user can use up to 1 G, as an upper limit of total communication amounts of the smart phone and the tablet (for example, smartphone: 0.7 GB and tablet: 0.3 GB, etc.).

The user can make a contract with the MVNO carrier C, for example, from the integrated service providing site of the MVNO carrier C (cloud operator) using the user account. For example, the user can select according to a characteristic of each carrier, such as a carrier A being No. 1 as for ease of connection, while a carrier B being No. 1 as for line stability, contract fee, or the like.

According to the basic mode of the present invention, as described above, when a plurality of terminals owned by a user contracting with the MVNO carrier C uses the communication network of the carrier A or the carrier B, charging will be unified, regardless of whether the communication network of the carrier A or the carrier B is used. Even when the same terminal uses the communication network of the carrier A and the communication network of the carrier B, with SIM cards of the carrier A version and the carrier B version replaced, charging may be also unified.

According to the basic mode of the present invention, regarding a terminal contracting with a virtual communication operator providing a communication service by borrowing communication facilities owned by a plurality of communication carriers, it is possible to manage charging collectively for the plurality of communication carriers.

Furthermore, according to the basic mode f the present invention, it is possible to perform unified management of the charge related to communication and the charge related to a service (s) that can be provided to the user, based on user identification information.

Example Embodiment

FIG. 4 is a diagram illustrating an example embodiment of the present invention. FIG. 4 illustrates an example in which the basic configuration of FIG. 3 is implemented in FIG. 2. Also in FIG. 4, as with FIG. 2, the MVNO carrier C borrows facilities such as a base station 10A, EPC 20A, etc., and a base station 10B, EPC 20B, etc., lent respectively by a MNO carrier A and MNO carrier B. It is noted that in FIG. 4, the data center 50 in FIG. 2 is omitted. In FIG. 4, base stations 10A and 10B, EPC networks 20A and 20B, PCRF databases 24A-1 and 24B-1, and the Internet 30 are the same as those in FIG. 2 and the description thereof will be omitted.

The EPC network 40 may be the same as the EPC network 40 in FIG. 2 (virtual EPC (vEPC), or EPC configured by actual machines). Although a PCRF database 44-1 of the EPC network 40 in FIG. 4, is not illustrated in FIG. 2, it may be mounted on the virtual EPC 40 of the data center 50 in FIG. 2, for example.

The essential difference between the example embodiment of FIG. 4 and the related invention of FIG. 2 is that the example embodiment includes a cooperation database 45 (database (DB) associated with PCRF database 44-1). A service (including a communication service) is provided to a user based on information in the cooperation database 45, and a withdrawal is automatically made.

The MVNO carrier C uses respective user's accounts (for example, “aaa@example.com”, “bbb@example.com”) for charging management of terminals 1A and 1B. The user account may be such as account information established by the user at the integrated service providing site (Web site) of the MVNO carrier C, and it may also be a free e-mail address such as Web mail, for example. Further, as described above, when the user account is an arbitrary ID, an electronic mail address associated with the ID corresponds to the user account. The cooperation database 45 may be managed by an authentication server (not illustrated). It is noted that in FIG. 4, IMEIs (International Mobile Equipment Identity: 15 digits starting with 35) of the terminals 1A and 1B are simply expressed by three digits, such as 111 and 222, only for simplicity's sake.

The cooperation database 45 includes an account linkage table 45-1 to hold account information of the integrated service providing site of the MVNO carrier C, IMEI (Primary Key (PK): information for uniquely identifying a set of data sets (records) from the database), and information such as a charging method.

Based on the correspondence (linkage) between the account information (user account) in the account linkage table 45-1 of the cooperation database 45 and an IMEI (PK) of the terminal, linkage of the statistical information table 44-2 of the PCRF database 44-1 and information of the contractor information table 44-3 (both including IMEI) is performed. Thus, it is possible to calculate communication charge, call time, call charge, and the like, based on the user account. As for a call time calculated for a terminal that can use Wi-Fi Calling (a function of sending and receiving calls and SMS using Wi-Fi (registered trademark)), a call time by 3G (3rd Generation), 4G (4th Generation), or 5G (5th generation) and a call time by Wi-Fi Calling may be separately calculated. Further, the call charge may be calculated by setting charges different on per time based on the user accounts.

FIG. 5 is a diagram schematically illustrating an example of information retained in the PCRF database 44-1 and the cooperation database 45 in FIG. 4.

Referring to FIG. 5, the statistical information table 44-2 of the PCRF database 44-1 included in the PCRF 44 (server) stores IMEI (PK) of the terminal of the user contracting with the MVNO carrier C, packet count value, call time (duration), call charge (¥) and packet charge (¥).

When the MVNO carrier C borrows the communication facilities from the MNO carriers A and B to provide the communication facilities to the user as a communication facility of the MVNO carrier C, a packet count value, call time, call charge (¥), and packet charge (¥) in the statistical information table 44-2, are calculated in such a way that

a packet count value, call time, call charge (¥), and packet charge (¥), which the user terminal 1A (on which a carrier A version SIM card is inserted) uses the communication network of the MNO carrier A; and

a packet count value, call time, call charge (¥), and packet charge (¥) for the terminal 1B on which (the carrier B version SIM card is inserted) and that has the same user account as the user account of the terminal 1A, are summed up and consolidated. In the statistical information table 44-2, as for summing of the call charge (¥) and summing of the packet charge (¥) in the communication network of the MNO carriers A and B of the terminal 1A and the terminal 1B, instead of simple addition of the charge of each carrier, a calculation using a unique charge calculation system such as a weighted addition with predetermined weight coefficients, based on the call charge (¥) and the packet charge (¥) of the communication network of the MNO carriers A and B, and based on the contract with the MNO carriers A and B, may be applied.

The contractor information table 44-3 includes information items such as IMEI (PK), calling plan (upper limit, etc.), packet plan (upper limit etc.), communication limit information, account, name and address, communication permission/non-permission, etc. of a user's terminal contracting with the MVNO carrier C.

A call plan (upper limit, etc.), packet plan (upper limit, etc.), and the communication limit information in the contractor information table 44-3 correspond to a call plan (upper limit, etc.), packet plan (upper limit, etc.), and the communication limit information obtained by summing those of the terminal 1A (on which a carrier A version SIM card is inserted) using the communication network of the MNO carrier A and the terminal 1B (on which a carrier B version SIM card is inserted) using the communication network of MNO carrier B.

The account linking table 45-1 of the cooperation database 45 includes information items such as IMEI (PK), account, account charging method, prepaid reserve capacity of the account (balance of the prepaid account), charging method (prepaid method or credit card payment), etc, of a terminal. These items of information may be set from a management terminal (apparatus) of the MVNO carrier C, based on relevant information on which a user contracts with the MVNO carrier C. When the user's terminal uses the communication network of the MVNO carrier C or a service provided by the integrated service providing site of the MVNO carrier C (electronic book purchasing, etc.) (51), settlement is performed with reference to the cooperation database 45, and a use notification (withdrawal notification) is made (52).

Instead of unified charging management using the account, such as option of individually performing charging management for each user's terminal is available by setting of the account charging method in the account pegging table 45-1 of the cooperative database 45. In this case, a user, who is a subscriber of the MVNO carrier C and possesses a plurality of terminals (smart phone and tablet), can receive individually usage details of each terminal, with the MVNO carrier C performing charging management individually for each terminal. In the present example embodiment, as described above, the MVNO carrier C perform unified charging management for different carriers (MNO carriers A and B), based on a user account. However, instead of unified charging management for different carriers, when a user owns a plurality of terminals that use a communication facility of the same carrier (MNO carrier A, for example), charging for the plurality of terminals may, as a matter of course, be unitarily managed based on the user account (together with the charging for use of a service(s) other than user's communication, and call). That is, when a user of the MVNO carrier C owns a plurality of terminals having a SIM card of the carrier A in FIG. 4, packet count values, call time, call charge, packet charge, etc., of the plurality of terminals are linked by a user account common to the plurality of terminals, and a unified charging information into which charging information of the plurality of terminals are consolidated, is notified to the user.

FIG. 6 is a diagram illustrating an operation of the example embodiment illustrated in FIGS. 4 and 5. The operation sequence of the present example embodiment will be described with reference to FIG.

(1) A communication request is made from the terminal (for example, 1A in FIG. 4) to the EPC network 40 of the MVNO carrier C via the base station (for example, 10A in FIG. 4). At that time, IMEI information of the terminal is transmitted from the base station (for example, 10A in FIG. 4) to the EPC network 40 of the MVNO carrier C, using a predetermined message. (2) In the EPC network 40 (for example, PCRF 44, PCEF, PGW 42, etc.) of the MVNO carrier C, IMEI of the terminal, IMEI of the cooperation database 45, and IMEIs of the statistical information table 44-2 and the contractor information table 44-3 are collated. If the collation result of the IMEI of the terminal is okay and a password authentication of the user account (performed by an authentication server not illustrated) is okay, then payment confirmation is performed. When the charging method for the terminal is of a prepaid type, a balance of the prepaid account is confirmed. If it is confirmed that a prepaid balance remains, it is judged that the terminal authentication and the payment confirmation are okay. (3) When both results of the terminal authentication and the payment confirmation are okay, communication of the terminal is allowed. When the communication is allowed, the communication service is provided to the terminal. (4) When the terminal authentication is not okay (in the case of NG (No good)), the communication of the terminal is not allowed. Even in the case where the terminal authentication is okay, if the payment confirmation is not okay, the communication of the terminal is not allowed. It is noted that regarding a terminal, if the terminal authentication thereof is okay and the payment confirmation thereof is not okay (NG), PGW (42 in FIG. 5) and so forth may allow the terminal to perform communication at low-speed communication (for example, 128 kbps), for a predetermined period, based on policy setting by PCRF (44 in FIG. 5), and PCEF). (5) As a result of the communication permission, the communication service by the MVNO carrier C is provided to the terminal, and the communication amount of the terminal is measured. The communication amount of the terminal is totaled up, every month, every day, or at an arbitrary timing (online), and the packet count value and the like of the statistical information table 44-2 are updated.

As an option, the communication data amount of a predetermined application can be excluded from the packet count. A data destination, a data header, and so forth may be collated to a predetermined list, and matched data may be excluded from the packet count.

(6) The MVNO carrier C executes charging processing, monthly, daily, or at an arbitrary timing. A predetermined fixed fee or a fee corresponding to a communication amount may be withdrawn. At that time, account information of the cooperation database 45, charging method, and account information (credit card number) are acquired. (7) The MVNO carrier C charges the usage fee of the terminal (7A) to a card company 70, or performs prepaid processing (7B). (8) The integrated service providing site of the MVNO carrier C (site (server) providing the service 51 in FIG. 5) notifies usage details to the user account via notifying unit 52-1, such as electronic mail (for example, Web mail etc.) or the like. (9) The usage details (for example, basic monthly fee, packet flat rate fee, communication and call charges, etc) are notified to the user's terminal. When the charging method is payment by credit card, details on withdrawal from the credit company is sent to the user, for example, one month behind.

<Charging Apparatus>

FIG. 7 is a diagram illustrating an example of a configuration of a charging apparatus (charging server) 60 of the MVNO carrier C. The charging apparatus (charge management apparatus) of the MVNO carrier C is connected to the EPC network 40, the PCRF database 44-1, and the cooperation database 45 in FIG. 4. The charging apparatus of the MVNO carrier C may be provided in the data center (50 in FIG. 2) owned by the MVNO carrier C.

Referring to FIG. 7, the charging apparatus 60 includes a contractor information collation unit 61, a communication charge calculation unit 62, other service charge calculation unit 63, unified charge calculation unit 64, payment processing unit 65, and a usage details notification unit 66.

The contractor information collation unit 61 collates the terminal identification information (IMEI) with the user's account information, to make a linkage therebetween. The communication charge calculation unit 62 acquires communication charge and call charge from the PCRF database 44-1 with respect to each terminal (on which a SIM card of the MVNO carrier C is mounted) of the IMEI corresponding to a user's account. When the user owns a plurality of terminals (on each of which a SIM card of the MVNO carrier C is mounted) with the same account, the communication charge calculation unit 62 calculates communication charge and call charge of each terminal from the PCRF database 44-1 The other service charge calculation unit 63 acquires charging information of a service (for example, electronic book purchasing, music delivery, etc.) provided by the integrated service providing site of the MVNO carrier C.

The unified charge calculation unit 64 sums up charges from the communication charge calculation unit 62 and the other service charging calculation unit 63. The payment processing unit 65 either withdraws a predetermined fixed fee, on a monthly or daily basis, or at an arbitrary timing, or withdraws a fixed fee corresponding to the communication amount. That is, the payment processing unit 65 either requests the usage charge to the credit card company (70 in FIG. 6) with a credit card number, or withdraws from the prepaid balance. The usage details notification unit 66 creates usage details in response with a monthly, daily, or an arbitrary timing withdrawal, and transmits to the user the usage details, for example, by electronic-mail (for example, Web mail) or the like.

Even if the user has a separate contract with a MVNO carrier regarding each of a plurality of terminals owned by the user, using a common user account (contract contents for the terminals such as quota are different), monthly usage details may be done once in a single notification in which a total charge amount of the plurality of terminals is included and a communication charge or the like of each individual terminal may be described by breakdown of the details.

In FIG. 7, a part or all of functions of the contractor information collation unit 61, communication charge calculation unit 62, other service charge calculation unit 63, unified charge calculation unit 64, payment processing unit 65, and the usage details notification unit 66 may, as a matter of course, be realized by a program executed on a computer such as a server. The program may be stored in a storage unit (a hard disk drive unit or a semiconductor storage unit or the like) (not illustrated), loaded into a main memory of the computer, and executed.

As a variation example of the example embodiment, with respect to the user's terminal, when a prepaid reserve capacity (balance) of the terminal in the cooperation database 45 becomes equal to or less than a predetermined value or the balance becomes 0, the fact may be notified via the notifying unit 52-1 to the terminal of the user. A low-speed communication (for example, 128 kbps) of the terminal for a predetermined period of time, may be allowed under the above described communication policy control made by OCS, PCRF, PCEF, PGW, etc., even when a prepaid balance of the terminal is zero and not charged.

According to the example embodiment, it is possible to perform unified charging for one or more terminals contracting with a MVNO carrier that borrows communication facilities owned by a plurality of carriers and provides communication services, thereby improving convenience and services. In addition, it is possible to enhance convenience and increase usage of a site(s) that provides various services by unifying charging to a user who uses the site(s) and charging to the user contracting with the MVNO carrier.
